2 Expanding Mandrels Power Expanding Mandrels for Lathes Rigid and Accurate Workholding for Internal Diameters Internal Clamping Offers Full Part Access Allows for full access to the entire external profile of the workpiece so all external diameters can be turned in a single operation, guaranteeing perfect concentricity. Quick & Easy Mounting Klamp expanding mandrels mount directly to the lathe spindle or use a precision adaptor plate to ensure a consistent mounting without the need for correction. The precision fit of the Klamp collet chuck enhances the rigidity of the overall system. The need for adjustment is minimal, meaning less machine down-time. High Accuracy & Rigidity Pull-back design draws the workpiece securely against a part locator for dual-contact rigidity. Modular Design All Mandrel models have a common flange configuration, enabling full interchangeability with all back bodies. Parallel Expansion for Optimum Accuracy and Grip Force The Klamp double-angle design provides parallel sleeve expansion, ensuring full-length part contact and positive release when the part is unclamped. Two Regular Sleeve Types Available Customised Systems Available s Cost effective sleeves where the expander pin is outside the sleeve body, with either a 0.5mm or 0.8 gripping range (see pages for more detail), suitable for through bores and operated with a part locator. Dual sleeves (as shown above), extended length sleeves, 1/2 length sleeves and larger diameter sizes are on the market with up to 635mm ID gripping for supporting a wide range of parts. sleeves Expander pin is inside/level with the sleeve body with either a 0.5mm or 0.8 gripping range (see pages for more detail), suitable for blind bores and enables the sleeve to grip as much of the internal diameter as possible. A KEM dual sleeve system mounted on a rotary table. Actuated via a hydraulic cylinder and supported via a special hydraulic tailstock this setup is perfect for automated machining cells allowing multiple parts to be robot loaded and machined at the same time. 48
